A 53-year-old man from Memphis was stabbed downtown outside the Lollapalooza music festival while trying to scalp tickets last night, according to police and the fire department.

The man remains hospitalized in good condition late Saturday morning, according to Northwestern Memorial Hospital spokeswoman Lindsey Fox.

The victim told police he was standing on the northwest corner of Jackson Boulevard and Michigan Avenue selling tickets at 6:57 p.m. when he was confronted by a group of four younger men who tried to snatch the tickets out of his hand, police said.

The victim held onto the tickets and ran away, crossing the street as the four pursued him and surrounded him at the corner of Adams Street and Michigan while continuing to try and rob him, police said.

He was trying to push them back when one of the four – a black man between the ages of 19 and 25 and wearing a red baseball cap, a black shirt, and black shorts -- came from this left side, reached across, and stabbed the 53-year-old man, police said.

A passerby called 911 after the victim cried out for help and he told responding officers that the four ran away southbound on Michigan Avenue and west to State Street. It was not clear if they took the tickets.

The Memphis man suffered a stab wound to the upper center part of his abdomen and needed stitches, police said. Chicago Fire Department spokeswoman Meg Ahlheim said he was taken to Northwestern Memorial Hospital where his condition had stabilized Friday night.

A second suspect had a slim build, was wearing a red cut-off tank top, and was also black with a dark complexion. The third and fourth suspects were only described as black men between the ages of 19 and 25, police said.

Detectives were scouring the big crowds in and around Grant Park for witnesses.

About 100,000 tickets a day were bought for the sold-out three day Lollapalooza music festival that began Friday in Grant Park.
